Key swine veterinary practitioners describe the “PRRS-ception” of this disease in the most important pork producing regions.
Carmen Alonso García-Mochales
University of Minnesota (United States). Spain
Dr. Carmen Alonso was born in Madrid (central Spain). She graduated from the Complutense University of Veterinary Medicine in Madrid in 2003 with a postgraduate specialization in Swine Production Medicine from the Autonoma University of Barcelona in 2004. Following that, Dr Alonso worked as a swine practitioner in the Canary Islands, participating in a swine disease eradication project on 4 of the islands in this southeastern province of Spain (Tenerife Province).
Dr Alonso then moved her residence to the Spanish province of Catalonia in 2005 and joined the veterinary swine group at the Cooperative d’Ivars (a farmer owned cooperative of 40,000 sows). Catalonia is one of the most important swine production regions in Europe. She worked at this cooperative for 5 years in swine health and production consultation.
From 2010-2016, Dr. Alonso worked as a research assistant at the University of Minnesota while completing her MSc (The use of Air Filtration and its economic analysis for the entry of the PRRS virus into large sow herds within swine dense regions) and her PhD (Concentration, size distribution, and control of swine viruses associated with airborne particles).
In 2016, Dr. Alonso joined Elanco as a Elanco Knowledge Solutions senior consultant in swine analytics. She participated in several data analysis projects for Elanco clients globally.
Currently, Dr. Alonso is based in Barcelona (Spain) and runs her own business as an independent data analysis consultant for the swine industry. Her client base includes large swine production systems and pharmaceutical companies.

Total born, use of toxin binder, farrowing assistance and health status show an association with sow mortality due to uterine prolapses.
Percentage of prolapsed sows has consistently increased every year, from 4.8 in 2012 to 10.2% in 2016.
The most direct strategy to decrease the concentration in the air of airborne pathogens is dust reduction. This article describes the use of a particle ionization system called EPI.
A simple system that uses plastic and adhesive tape to prevent the entry of unfiltered air into a barn can also serve as a safe method to prevent inappropriate non-biosecure personnel movement.
The installation of physical barriers at strategic personnel entry points help to define distinct biosecurity areas. This method is commonly used in farms that lack a clear separation between areas with different biosecurity levels.
The use of plastic and gravel to prevent the growth of vegetation around the perimeter of the barn. This is a simple strategy that will also decrease the chances for rodents to enter the facilities and it will help improve external barn biosecurity.
This study demonstrates the added profitability that air filtration can give to sow farms located in highly dense swine regions. However, it is important to point out that these figures are long term averages and not necessarily predictors for individual herds.
